Tighten bolts alternately to 10 Nm.
2. Install belt drive pulley on crankshaft:
- Install belt drive pulley using the center nut and spacer.
- Install oil thermostat casing, using new O-ring.
NOTE: Do not let crankshaft rotate, as this may damage valves.
3. Install:

- Coolant pump, using new gasket.
Tighten bolts alternately to 20 Nm (15 ft lb).
- Thermostat and thermostat casing, using new gasket.
4. Fit upper timing belt cover:
- Install camshaft pulleys.
Align timing marks as shown.
- Insert two bolts in each pullet, tightening until just in contact with pulley.
- Lift upper timing belt cover off.
NOTE: Check that camshaft bolt holes are centered as illustrated.
5. Reinstall:
- Idler pulley, tighten to: 24 Nm (17.3 ft lb)
- Tensioner pulley, apply grease to surfaces of the actuator arm bushing, screw and sleeve.
Use lubricant part No. 1 161 246-2, or equivalent.
Tighten to: 30 Nm (22 ft lb)
- Tensioner/damper unit, tighten to: 24 Nm (17.3 ft lb)
6. Install timing belt:
- Place belt over camshaft pulleys, around water pump and press over tensioner pulley.
- Slacken two camshaft pulley bolts.
Remove locking pin from belt tensioner.
- Lock belt by tapping lightly (twice) with a plastic mallet between the camshaft pulleys and between the water pump and camshaft pulleys.
- Install plastic throw control washer.
- Install third bolt in each pulley and tighten all bolts to: 20 Nm (15 ft lb).
- Install upper transmission cover and belt guard.
7. Remove locking tools:
- Remove crankshaft locking tool No. 999 5451, or equivalent and install plug with new copper seal.

- Use drift tool No. 999 5450, or equivalent.
- Grease seals.
- Press seals home until drift stops.
NOTE: If shaft ends show sign of wear, seal can be pressed in another 2 mm by turning tool sleeve.
9. Install vibration damper:
- Install vibration damper using counterhold tool No. 999 5433, or equivalent.
- Tighten center nut to 180 Nm (132 ft lb).
- Remove counterhold.
Tighten bolts to 25 Nm plus 30° (18 ft lb).
10. Check markings:
